<p>Abstract</p> <p>Background</p> <p>Chronic inflammation is a characteristic of Alzheimer's disease (AD). An interaction associated with the risk of AD has been reported between polymorphisms in the regulatory regions of the genes for the pro-inflammatory cytokine, interleukin-6 (IL-6, gene: <it>IL6</it>), and the anti-inflammatory cytokine, interleukin-10 (IL-10, gene: <it>IL10</it>).</p> <p>Methods</p> <p>We examined this interaction in the Epistasis Project, a collaboration of 7 AD research groups, contributing DNA samples from 1,757 cases of AD and 6,295 controls.</p> <p>Results</p> <p>We replicated the interaction.
